| blackburn | I was in high school when house md first seasons were coming out | 00:01 |
|---|---|---|
| n4nd0 | yeah me too | 00:02 |
| blackburn | as I was doing nothing in school I watched it | 00:02 |
| n4nd0 | I watched house while in high school too | 00:02 |
| blackburn | I finished school in 2008 IIRC | 00:03 |
| blackburn | :D | 00:03 |
| blackburn | n4nd0: when did you? | 00:03 |
| n4nd0 | mmmmm | 00:03 |
| n4nd0 | I finished high school 6 years ago | 00:03 |
| blackburn | 2007 then I guess | 00:03 |
| n4nd0 | 2007 probably | 00:03 |
| n4nd0 | yeah | 00:04 |
| n4nd0 | I started uni when I was 17 | 00:04 |
| n4nd0 | now I am 23 | 00:04 |
| n4nd0 | so yeah 2007, indeed | 00:04 |
| blackburn | I am still 21 but 3 days lef | 00:04 |
| blackburn | t | 00:04 |
| n4nd0 | happy birthday!! | 00:05 |
| blackburn | hah | 00:05 |
| n4nd0 | haha | 00:05 |
| blackburn | my brother has b-day today | 00:05 |
| n4nd0 | happy birthday to him! | 00:05 |
| blackburn | yeah I'll let him know, thanks :) | 00:05 |
| n4nd0 | Saturday 16th yours right? | 00:05 |
| blackburn | yeah | 00:05 |
| blackburn | our parents were precise | 00:05 |
| n4nd0 | haha yeah | 00:05 |
| n4nd0 | older brother? | 00:06 |
| blackburn | 13 and 16 march but 7 years | 00:06 |
| blackburn | yes, 29 | 00:06 |

| blackburn | n4nd0: ^ something like that in d3.js would be ideal | 00:10 |
| n4nd0 | yeah | 00:10 |
| n4nd0 | I have to see how to do it | 00:10 |
| blackburn | https://dl.dropbox.com/u/10139213/shogun/pics.png | 00:10 |
| blackburn | n4nd0: http://bl.ocks.org/mbostock/950642 | 00:12 |
| blackburn | n4nd0: images as nodes | 00:13 |
| n4nd0 | cool | 00:21 |
| blackburn | n4nd0: http://bl.ocks.org/mbostock/1804919 that's an example of graph layout with 'suggested' position | 00:22 |
| blackburn | n4nd0: so you could change gravity function, add image nodes and that's it | 00:23 |
| blackburn | time to sleep | 00:24 |
| n4nd0 | ok | 00:27 |

| lambday | hi.. I've been writing a string kernel and I want to normalize the it... how do I do it? | 10:07 |
| lambday | I've set the normalizer in the constructor as set_normalizer(new CSqrtDiagKernelNormalizer()); | 10:07 |
| lambday | and tried to use return normalizer->normalize(total, idx_a, idx_b); in the compute function but got a segmentation fault | 10:08 |
| blackburn | lambday: normalizer is being called in base CKernel class, no need to call it once more | 10:12 |
| lambday | but compute function returns the unnormalized kernel value :( | 10:12 |
| blackburn | lambday:https://github.com/shogun-toolbox/shogun/blob/master/src/shogun/kernel/Kernel.h#L234 | 10:16 |
| blackburn | lambday: compute should return unnormalized value as kernel() computes final value | 10:16 |
| lambday | blackburn: oh... I get it now.. | 10:17 |
| lambday | thanks a lot | 10:17 |
| sonne|work | lambday: just make sure that you call init_normalizer() in kernels' init(a,b) function | 10:25 |
| lambday | sonne|work: yes... I did and its working fine now :) | 10:26 |
| sonne|work | k | 10:26 |
| lambday | one more thing... I want to add this SSKStringKernel to modular interface... what exactly should I do? blackburn told me few days back that it needs to be added to interfaces/modular/Kernel.i, and Kernel_includes.i. | 10:26 |
| lambday | I see a few renames and includes in Kernel.i | 10:27 |
| blackburn | lambday: that's the only thing | 10:27 |
| blackburn | yes, rename and include in Kernel.i | 10:27 |
| blackburn | and just include in Kernel_includes.i | 10:27 |
| lambday | blackburn: okay... i'm checking | 10:28 |

| lambday | blackburn: thanks man... its working perfectly... the kernel matrix is symmetric.. tested with some data.. | 11:32 |
| sonne|work | lambday: now it only has to be positive :-] | 11:33 |
| lambday | how do i test its psd? | 11:33 |
| sonne|work | lambday: empirically? check if eigenvalues are positive | 11:36 |
| lambday | sonne|work: I gotta check it manually? :( | 11:39 |
| sonne|work | lambday: yeah proof it! | 11:40 |
| lambday | sonne|work: okay... | 11:40 |
| sonne|work | lambday: but don't worry if it is not - we have some 'kernels' in there that are not by theory but empirically everything is good | 11:42 |
| lambday | sonne|work: that sounds relaxing :) | 11:45 |
| lambday | I gotta check its performance on some protein test data... I should compare its performance against other string kernels... let's see :) | 11:47 |
| lambday | thanks a lot :) | 11:47 |

| blackburn | heiko: I have fixed something | 12:50 |
| heiko | blackburn: nice :)( | 12:50 |
| heiko | I am scanning the gpr framework | 12:51 |
| heiko | found some bugs | 12:51 |
| heiko | still results are nonsense | 12:51 |
| heiko | hope to finish this today | 12:51 |
| heiko | at least for regression | 12:51 |
| heiko | btw while looking through this, I think I will write a project description for GP classification for gsoc | 12:51 |
| heiko | spent whole yesterday evening with this gpr stuff, we really have to make people write tests | 12:53 |
| blackburn | heiko: I don't get a thing about GP - that's a lot of code I am quite lost within | 12:57 |
| heiko | blackburn: I know it should have been better documented/organised | 12:58 |
| heiko | the variable names are very misleading | 12:58 |
| heiko | but I am on it | 12:58 |
| blackburn | heiko: that's "-" of part-time gsoc development | 12:58 |
| blackburn | "+" is that we get some code though | 12:58 |
| heiko | blackburn: I think that is our fault | 12:58 |
| heiko | not the student's | 12:58 |
| heiko | since we did not make them | 12:58 |
| heiko | so lets do this differently this year | 12:58 |
| blackburn | heiko: exactly | 12:59 |
| heiko | I wont merge any new code without a unit test | 12:59 |
| blackburn | heiko: that's always management | 12:59 |
| heiko | and without loads of comments | 12:59 |
| blackburn | heiko: that's actually my PM who should be blamed I am reading about C++11 instead of doing something useful :D | 12:59 |
| blackburn | so yes, I agree | 12:59 |
| blackburn | heiko: it would be nice if you declare such principle on the mailing list | 13:00 |
| blackburn | I could send a scan of my sign :D | 13:00 |
| blackburn | heiko: there is an anecdote about russian diplomates | 13:01 |
| heiko | blackburn: yes? :) | 13:01 |
| blackburn | heiko: something like that: teachers asked future diplomates to write a letter to somalian pirates | 13:01 |
| blackburn | which would force to set hostages free | 13:01 |
| heiko | haha :) | 13:02 |
| blackburn | week later - teacher "nice, but assholes should be written without a space and you made some mistakes in word f*cking" | 13:02 |
| blackburn | heiko: that's a lame translation but I hope you get it right :) | 13:03 |
| heiko | I get it | 13:03 |
| heiko | well, we have the power to merge :) | 13:03 |
| blackburn | heiko: in russian it sounds funnier as we have infinite amounts of various blames | 13:04 |
| blackburn | heiko: so when you have some time and will, could you please write a manifest about that? | 13:05 |
| heiko | blackburn: I will, we can put it on the GSoC page | 13:05 |
| heiko | like guielines | 13:05 |
| heiko | on developing code | 13:05 |
| blackburn | heiko: yeap | 13:06 |
| heiko | blackburn: yeah I fixed the bug | 13:12 |
| heiko | blackburn: would have been easily catched by a test | 13:12 |
| heiko | caused by something that was developed after this first thing was checked | 13:12 |
| heiko | #but since not test, no detection that old breaks when new is added | 13:12 |
| blackburn | heiko: that's quite cool we all get importance of unit-tests | 13:13 |
| heiko | blackburn: sorry :) I am too keen on this | 13:13 |
| blackburn | heiko: no that's ok | 13:13 |
| blackburn | heiko: ideal case is first tests then code | 13:15 |
| heiko | blackburn: yes, code a module/method, add test, then use it in code | 13:15 |
| blackburn | heiko: it won't work with software you don't know how to write but for established stuff it is the only way | 13:15 |
| heiko | blackburn: well ideally one things of the stuff you gonna write before you do it right? :) | 13:16 |
| blackburn | heiko: well interface should be know first - so interface tests should come before real coding | 13:16 |
| blackburn | (ideal) | 13:16 |
| blackburn | heiko: one thing sklearn rocks with is that they have ->100% test coverage | 13:17 |
| heiko | i know | 13:18 |
| heiko | but we will increase ours ! | 13:19 |

| sonne|work | (I am serious here) | 14:17 |
| heiko | sonne|work: not doing | 14:17 |
| blackburn | sonne|work: that's interesting - motivate ;) | 14:17 |
| heiko | fixing | 14:17 |
| sonne|work | comments are not a good idea | 14:18 |
| heiko | ? | 14:18 |
| sonne|work | only for doxygen api use | 14:18 |
| blackburn | yeah that's true, code should be selfcommenting | 14:18 |
| sonne|work | heiko: if you need comments your code is not readable | 14:18 |
| heiko | sonne|work: I do not agree | 14:18 |
| heiko | I think it is very good to explain what one is doing | 14:18 |
| sonne|work | heiko: no | 14:18 |
| sonne|work | heiko: give the function a proper name | 14:18 |
| sonne|work | instead of calling it do_stuff | 14:19 |
| sonne|work | call it compute_variance etc | 14:19 |
| sonne|work | -> no comment necessary | 14:19 |
| heiko | its way easier to read "compute cholesky" than | 14:19 |
| heiko | cblas_dsymm(CblasColMajor, CblasLeft, CblasUpper, | 14:19 |
| heiko | m_ktrtr.num_rows, temp2.num_cols, (m_scale*m_scale)/(sigma*sigma), | 14:19 |
| heiko | m_ktrtr.matrix, m_ktrtr.num_cols, | 14:19 |
| heiko | temp2.matrix, temp2.num_cols, 1.0, | 14:19 |
| heiko | temp1.matrix, temp1.num_cols); | 14:19 |
| heiko | memcpy(m_kern_with_noise.matrix, temp1.matrix, | 14:19 |
| heiko | temp1.num_cols*temp1.num_rows*sizeof(float64_t)); | 14:19 |
| heiko | clapack_dpotrf(CblasColMajor, CblasUpper, | 14:19 |
| heiko | temp1.num_rows, temp1.matrix, temp1.num_cols); | 14:19 |
| heiko | m_L = SGMatrix<float64_t>(temp1.num_rows, temp1.num_cols); | 14:19 |
| blackburn | heiko: eigen3 :) | 14:19 |
| heiko | blackburn: I did not write that! :) | 14:19 |
| blackburn | true | 14:19 |
| sonne|work | heiko: yes but call it compute_cholesky | 14:19 |
| sonne|work | and put it in a function | 14:20 |
| heiko | sonne|work: also sometimes its good to describe what the next section will be doing | 14:20 |
| sonne|work | no code needed | 14:20 |
| sonne|work | heiko: no! | 14:20 |
| sonne|work | exactly not! | 14:20 |
| sonne|work | if you want to comment what the next section does | 14:20 |
| blackburn | heiko: matrix.ldlt().solve(rhs) | 14:20 |
| sonne|work | put it in a function and give it a self-describing name! | 14:20 |
| blackburn | heiko: ^ eigen3 way | 14:20 |
| sonne|work | heiko: btw what is the state about this GP stuff? | 14:20 |
| heiko | sonne|work: I do not agree, of course this is what one should do, but still, sometimes comments are needed. | 14:21 |
| heiko | sonne|work, I solved the bug that made the basic GPR return nonsense | 14:21 |
| sonne|work | very extremely rarely | 14:21 |
| sonne|work | nice! | 14:21 |
| heiko | and wrote many tests to check | 14:21 |
| heiko | but now | 14:21 |
| heiko | it crashes depending on size of test data | 14:21 |
| heiko | (it did that before) | 14:21 |
| heiko | so investigating .... | 14:21 |
| heiko | at least the regression works if it terminates | 14:22 |
| heiko | blackburn: I know, but I am not going to change all these calls :) (as long as they work) | 14:23 |
| blackburn | heiko: just persuading you to join the dark side | 14:24 |
| heiko | hey, I use eigen3 for my current project! :) | 14:24 |
| heiko | btw exactly this call you mentioned :) | 14:24 |
| blackburn | heiko: then I am helping you with motivation to not left the dark side :) | 14:25 |
| heiko | hehe | 14:25 |
| heiko | blackburn: maybe I should use eigen3, there is an error in the cholesky for certain matrix sizes | 14:27 |
| heiko | blackburn, whats the best way to convert a shogun matrix into an eigen3 one? | 14:28 |
| heiko | I think thats the problem, there is some uninitialised memory | 14:29 |
| blackburn | heiko: Map class | 14:29 |
| blackburn | heiko: Map<MatrixXd>(pointer,cols,rows) | 14:30 |
| blackburn | heiko: act just like with typical matrix afterwards | 14:31 |
| heiko | Map class of eigen3? | 14:31 |
| heiko | so this returns a 2d array? | 14:31 |
| blackburn | heiko: yes, just like MatrixXf | 14:33 |
| blackburn | or MatrixXd | 14:33 |
| heiko | nice, what about K^T * x , blackburn? | 14:39 |
| heiko | how do I do that? | 14:39 |
| heiko | will get lunch now, see you in a bit | 14:40 |
| blackburn | heiko: K.transpose()*x | 14:43 |

| blackburn | heiko: no, y = K*transpose()*x will form it inplcae | 15:12 |
| heiko | blackburn: I see thanks | 15:12 |
| blackburn | but just K.transpose()*x does nothing | 15:12 |
| heiko | blackburn, LLT | 15:13 |
| blackburn | heiko: mutable stuff is in array mainly | 15:13 |
| heiko | does it change the given matrix? | 15:13 |
| blackburn | heiko: solveInPlace() | 15:13 |
| blackburn | I think you need it if you want to change it | 15:13 |
| heiko | blackburn: is there any example eigen code in shogun that I could borrow some things from? | 15:16 |
| blackburn | heiko: argh wait that's not true | 15:16 |
| blackburn | heiko: LLT computes a copy | 15:16 |
| blackburn | yes | 15:16 |
| blackburn | heiko: https://github.com/shogun-toolbox/shogun/tree/master/src/shogun/lib/malsar | 15:16 |
| blackburn | these algorithms are made of eigen | 15:17 |
| heiko | Map<VectorXd> Mzp_DiagSigz(x,n_tasks);Mzp_Pz = eigensolver.eigenvectors().real(); | 15:17 |
| blackburn | heiko: yeah I had to keep naming to track with original implementation | 15:18 |
| heiko | no worries, just asking whether this map is then the 2d array? | 15:18 |
| blackburn | heiko: yes, a vector of variable length (X) and (d)ouble type | 15:19 |
| blackburn | heiko: this code adhere Mzp_DiagSigz to pointer x | 15:19 |
| blackburn | and then steal eigenvectors I guess | 15:19 |
| blackburn | I don't remember exactly how can that work though | 15:20 |
| blackburn | :D | 15:20 |
| blackburn | eigenvectors must be a matrix.. | 15:20 |
| heiko | blackburn: | 15:21 |
| heiko | sorry I always have problems with new frameworks | 15:22 |
| heiko | what is the code | 15:22 |
| heiko | I have a shogun matrix , I want to turn it into MatrixXd | 15:22 |
| heiko | or similar | 15:22 |
| blackburn | heiko: map is the thing you need | 15:22 |
| heiko | how | 15:23 |
| heiko | Map<MatrixXd> K(m_kern_with_noise.matrix, m_ktrtr.num_rows, | 15:23 |
| heiko | m_ktrtr.num_cols); | 15:23 |
| heiko | I did this | 15:23 |
| heiko | now I want to add something to the diagonal, how do I do that? | 15:23 |
| heiko | how to get the MatrixXd instance? | 15:23 |
| heiko | blackburn: ah I finally found the documentation site :) nevermind | 15:24 |

| blackburn | heiko: asDiagonal() += vec | 15:27 |
| blackburn | K.asDiagonal().array() += vec | 15:27 |
| blackburn | sth like that IIRC | 15:27 |
| blackburn | heiko: but actually yes they have not that bad doc | 15:28 |
| blackburn | some things are not clear though | 15:28 |
| blackburn | I asked about some thing once on their channel | 15:28 |
| blackburn | the answer I got was 'check doc' | 15:28 |
| blackburn | go figure :D | 15:28 |
| heiko | ha | 15:28 |
| heiko | so now I have a MatrixXd | 15:30 |
| heiko | how to get the 2d array? :D | 15:30 |
| blackburn | heiko: what do you mean by array? | 15:32 |
| sonne|work | blackburn: double[] | 15:32 |
| heiko | yes | 15:32 |
| blackburn | heiko: K.data() | 15:32 |
| heiko | thanks! | 15:33 |
| blackburn | that's pointer for me | 15:33 |
| blackburn | :D | 15:33 |
| heiko | blackburn, what I am trying to do: | 15:34 |
| heiko | I have a shogun matrix | 15:34 |
| heiko | and I want another shogun matrix of the cholesky of it | 15:34 |
| heiko | so it seems like I have to copy the data twice | 15:34 |
| heiko | or once? | 15:34 |
| heiko | or at all=? | 15:34 |
| blackburn | heiko: first map | 15:36 |
| blackburn | existing matrix | 15:36 |
| blackburn | you get Map<MatrixXd> | 15:36 |
| blackburn | then prepare llt() | 15:36 |
| blackburn | ahh I see what you mean | 15:36 |
| blackburn | yes matrix would try to shoot your leg if you just steal the matrix | 15:37 |
| blackburn | * the array | 15:37 |
| heiko | yes, I need to store the llt suff | 15:37 |
| heiko | so I need to memcpy right? | 15:38 |
| blackburn | heiko: yes I think so | 15:38 |
| blackburn | heiko: but I'd avoid memcpy here | 15:38 |
| heiko | so what to do? | 15:39 |
| blackburn | heiko: I don't like that solution | 15:39 |
| blackburn | heiko: just copy values with for | 15:39 |
| blackburn | heiko: but again that feels wrong, let me check | 15:40 |

| blackburn | heiko: why do you need it btw? | 15:41 |
| heiko | blackburn: because the GP code stored the L for late ruse | 15:41 |
| blackburn | can't you store LLT? | 15:41 |
| blackburn | ahh | 15:41 |
| heiko | and I dont want to store an eigen object | 15:41 |
| blackburn | heiko: alright, copying is quite bad though | 15:42 |
| heiko | why? isnt it faster than for | 15:42 |
| blackburn | heiko: I mean in general I don't like that you've got to copy it twice | 15:43 |
| heiko | it is only once right? | 15:43 |
| heiko | the map should not copy? | 15:43 |
| blackburn | heiko: I think I got a solution | 15:43 |
| heiko | or does llt copy? | 15:43 |
| blackburn | okay | 15:43 |
| blackburn | you have SGMatrix G | 15:43 |
| heiko | lets call it K | 15:43 |
| blackburn | you create Map<MatrixXd> K | 15:43 |
| blackburn | okay | 15:43 |
| blackburn | sgK | 15:43 |
| blackburn | and eigK | 15:43 |
| blackburn | you also have matrix SGMatrix L | 15:44 |
| heiko | eigK is the ma?p | 15:44 |
| blackburn | which is cholesky factor | 15:44 |
| blackburn | you add Map<MatrixXd> eigL | 15:44 |
| blackburn | and | 15:44 |
| blackburn | eigL = eigK.llt().matrixL(); | 15:44 |
| heiko | I see | 15:44 |
| heiko | good idea | 15:44 |
| heiko | btw how to I get upper? | 15:44 |
| blackburn | heiko: that sounds like a most efficient way to do that | 15:44 |
| heiko | like in matlab? | 15:44 |
| blackburn | heiko: matrixU but what is upper? | 15:44 |
| blackburn | do you need it? | 15:45 |
| heiko | the upper triangular part | 15:45 |
| heiko | yes | 15:45 |
| blackburn | heiko: alright then matrixL and matrixU | 15:45 |
| heiko | ok | 15:45 |
| heiko | thanks | 15:45 |
| heiko | I will try ... | 15:45 |
| blackburn | heiko: these matrices are actually a views | 15:45 |
| blackburn | heiko: ah btw if your K is symmetric | 15:46 |
| blackburn | K.selfadjointView<Eigen::Upper>().llt().matrixU() | 15:47 |
| blackburn | that can be more efficient | 15:47 |
| -!- FSCV [~FSCV@vpnreactor-static44.den.icastcenter.com] has joined #shogun | 15:47 | |
| heiko | what does it do? | 15:48 |
| blackburn | heiko: it tells eigen that your matrix can be treated as selfadjoint | 15:49 |
| blackburn | thus all operations that can improve from that would improve from that | 15:50 |
| blackburn | heiko: for example I use it in PCA-like algorithms | 15:50 |
| blackburn | covariance is C.selfadjointView<Eigen::Upper>().rankUpdate(v,v,1.0); | 15:50 |
| blackburn | rank update is C <- C + alpha*x*x' - it is done much faster then you know C is symmetric | 15:51 |

| blackburn | heiko: are you talking about the bug? | 16:06 |
| heiko | blackburn: plural, but no | 16:06 |
| heiko | the thing about storing the factor | 16:06 |
| heiko | say is there a way to solve a system with an existing cholesky? | 16:06 |
| heiko | llt.solve(b) | 16:06 |

| blackburn | heiko: they didn't expect such thing I guess :) | 16:09 |
| heiko | blackburn: mmh that is annoying | 16:09 |
| heiko | I mean | 16:09 |
| heiko | currently the GP framework solves again anyway | 16:09 |
| heiko | but it would be good not to do that | 16:09 |
| heiko | uuuh | 16:10 |
| heiko | there are so many bugs | 16:11 |
| heiko | its not possible to deal with all of them | 16:11 |

| heiko | just had a break | 18:07 |
| heiko | blackburn: heureca, it works! | 18:31 |
| heiko | blackburn: multiclass ocas test fails | 18:45 |
| blackburn | heiko: alright | 18:49 |
| blackburn | heiko: mc ocas then | 18:49 |
| blackburn | heiko: what was wrong with gps? | 18:51 |
| heiko | blackburn: two things: | 18:51 |
| heiko | a wrong feature object was used at a place so the thing was doing a different thing that it should have | 18:52 |
| heiko | and a lapack method was wrongly called, causing memory errors/crashes | 18:52 |
| heiko | seems to work quite nice now | 18:52 |
| heiko | but only tested the basic GPR | 18:52 |
| blackburn | I am going to update tapkee in shougn now | 18:52 |
| heiko | which is only a small part of the framework | 18:52 |
| blackburn | and then check mc ocas | 18:52 |
| heiko | blackburn: no | 18:52 |

| heiko | I suggest | 18:52 |

| blackburn | I am not sure if I should include it too | 19:48 |

| heiko | tests? | 19:48 |
| blackburn | yeah | 19:48 |
| heiko | dont know | 19:48 |
| blackburn | heiko: yeah me too | 19:48 |
| heiko | is it that distinct? | 19:48 |
| blackburn | the code of tapkee is just the same | 19:49 |
| blackburn | in standalone and in shogun | 19:49 |
| blackburn | so in principle they are not really required | 19:49 |
| heiko | I would say yes since then we can see them from shogun | 19:49 |
| blackburn | but tests for interface of tapkee in shogun (CClasses) should be here for sure | 19:49 |
| heiko | you know, I dont have to get involved into yet another framework then :D | 19:49 |
| blackburn | heiko: heh I use gtest too | 19:50 |
| blackburn | so I can just put them directly.. | 19:50 |
| blackburn | heiko: almost no alternative to gtest for C++ I think | 19:51 |
